A LAB-TESTED SOLUTION.

Frustrated by the "Wild-West" state of the supplement industry, we sought an answer. Instead of trusting companies with no background in competitive athletics, we joined together to create D1 Lab, a supplement brand built by collegiate and professional athletes. 

At D1 Lab, any product that comes out of our shop is third-party tested by Informed Sport for banned substances and contaminants.

Supporting young athletes and military members:

At D1 Lab, we want young athletes to experience the joy of athletics, regardless of financial background. We partnered with Good Sports to convert D1 Lab sales into sports equipment for the next generation of athletes.

"These things we do that others may live."

The United States Air Force Pararescuemen (PJs) are the nation’s force of choice to execute the most perilous, demanding, and extreme rescue missions anytime, anywhere across the globe. We partnered with the Pararescue Foundation to support a community of military personnel who live in service of others.
